WHEEL.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed June 27, 1906. Serial No. 323,612.

To all whom it may concern:

Be it known that I, JOSEPH SCOTFORD MILLER, a citizen of the UnitedStates, residing at Palmdale, in the county of Los Angeles, State ofCalifornia, have invented certain new and useful Improvements in Wheels;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to wheels, and more particularly totraction-wheels for mowers and similar implements, and has for itsobject to provide a wheel of the ratchet type which is revoluble withthe mechanism in one direction and independently thereof in the oppositedirection and which will be of such a structure that worn parts may beremoved for replacements.

It is to be understood that I do not desire to be limited to the exactdetails of construction shown and described, for obvious modificationswill occur to a person skilled in the art.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a view showing the present wheel in elevation and with thecap member removed. Fig. 2 is a vertical section through the wheel withthe cap member in position. Fig. 3 is an interior view-of the capmember, showing the arrangement of the dogs.

Referring now to the drawings, there is shown a wheel comprising a hubwhich includes an annular plate 5, having at its outer periphery acircular flange 6, extending at right angles thereto. Spokes 7 areengaged in and extend radially from this flange and carry a tread 8 attheir outer ends. An internal band-gear 9 is removably secured withinthe flange 6 by means of screws 10, which may be easily disengaged topermit of removal of the gear, and the central opening 5 of the plate 5receives the axle 11 of the mower. A cap member 12 receives the end ofthe axle within a central recess 13 and has a squared central opening14, which receives a squared projection 15 on the end of the axle, thisprojection having a cylindrical outer extremity, which extends beyondthe cap member and which is threaded, as shown at 16, for the receptionof a confiningnut 17. 1

The cap member extends just within the gear 9 and has pivoted thereto aplurality of dogs 18, springs 19 being arranged to hold the dogs inengagement with the teeth of the gear 9 for rotation of the wheel in onedirection with the axle, the arrangement being such as to permitmovement of the dogs against action of the springs to allow freerotation of the wheel upon the axle in the opposite direction. It willbe seen from the drawings that by reason of the fact that the cap is ofa size to pass through the internal gear the latter may be removed whenworn and a new one substituted therefor while the cap member is inposition.

What is claimed is The combination with an axle, of a wheel revolublymounted thereupon and including an annular plate through which the axlepasses, said plate having a continuous flange at its outer peripheryextending at right angles thereto, radial spokes carried by the flange,a tread carried by the spokes, and an internal gear removably securedwithin the flange, a cap member secured to the axle for movementtherewith, dogs pivoted to the cap member and engaging the gear forrotation of the wheel with the cap member and axle in one direction, andindependently thereof in the opposite direction, said cap member beingof a size to pass through the gear to permit of removal thereof when thecap is in position.

In testimony whereof I aflix my signature in presence of two witnesses.

J. S. MILLER.
